Bluetooth

I'm 99% sure that the iRulu does not have Bluetooth capability. The only slight doubt I have is because there is an option under Settings to enable "Bluetooth tethering".

UPDATE: While trying out HDMI at my friend's house, one of her housemates noticed an icon that I hadn't noticed that seemed to indicate an ability to do Bluetooth pairing. I had no Bluetooth device to try at the time. My suspicion is that there is no Bluetooth hardware, but some or all of the Android software to support Bluetooth is still present and may appear to be usable at times. Requires further testing.

The specifications do not mention Bluetooth, and, frankly, it was something I hadn't thought about--I didn't see a need / use for it.

Then I used Remote VOIP to make the tablet act as a VOIP phone, and now I can see a use for a Bluetooth headset.

But, then I decided to try looking for a USB headset and found lots of them. In addition, I found a little USB device to allow you to plug headphones and a microphone into the iRulu. I've ordered one (for $1.30). When I get it, I'll give it a try.
